The oriental melon poses challenges in terms of long-term storage and distribution. Addressing these issues requires an extension of the storage life through appropriate processing. In this study, pretreated hot-air dried oriental melon slices (steamed and freeze-thawed) were prepared, and their physicochemical and organoleptic properties were examined. The control group (CON) consisted of hot-air dried oriental melon slices without pretreatment, while the steamed group (STG) and freeze-thawed group (FTG) consisted of hot-air dried oriental melon slices pretreated using steaming and freeze-thawing methods, respectively. The moisture contents detected in the CON, STG, and FTG groups ranged from 15.96% to 27.30%, with variations of 7.53 to 8.40 °Brix for the soluble solid contents. The CON group showed the highest Hunter color value for lightness (L*) and the lowest value for redness (a*). The texture profile analysis revealed the highest hardness and chewiness in the order of STG > CON > FTG. Considerable differences were observed in springiness and adhesiveness in the FTG group compared to the other groups. The organoleptic evaluation showed that the CON group had the highest sensory scores for overall preference. These findings indicate that the properties of hot-air dried oriental melon slices were influenced by physical pretreatments and that manufacturing these slices without pretreatment is the most effective method in terms of processing simplicity and cost efficiency.

최근 우리 사회에도 다문화가정이 증가하고 있다. 만약 부모가 한국어에 익숙하지 않다면, 그 자녀들도 유아기 한글 학습에 지장을 받을 수 있다. 이에 따라 다문화가정 유아의 특성을 반영한 한글교육 프로그램이 필요하다. 본 연구는 그 초기 단계의 연구 결과물을 담고있다. 즉, 학습 콘텐츠 개발자-서버 관리자-학습자를 위한 시스템을 설계하였고, 지금까지 개발된 한글쓰기 교육용 앱의 초기 버전을 개발 완료하였다.

<P>Gene therapeutic approaches are needed that can simultaneously induce the well-controlled expression of therapeutic genes and suppress the expression of disease-causing genes for maximization of their efficacy. To address this challenge, we designed an allosteric ribozyme that comprises a <I>Tetrahymena</I> group I-based trans-splicing ribozyme as an active domain for RNA replacement, a small molecule-specific RNA aptamer as a sensor domain, and a communication module as an active transfer domain. The effectiveness of this approach was assessed by constructing various ribozymes in combination with a theophylline-binding aptamer to identify an allosteric ribozyme, which is controlled by theophylline both <I>in vitro</I> and in cells. Moreover, we constructed adenoviral vectors encoding the ribozymes and validated allosteric regulation of trans-gene expression via theophylline-dependent RNA replacement in target RNA-expressing cells. Results demonstrate that an allosteric trans-splicing ribozyme is an applicable RNA-based framework for engineering external ligand-controlled gene expression regulatory systems that exhibit adjustable regulation, design modularity, and target specificity.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/acbcct/2014/acbcct.2014.9.issue-11/cb500567v/production/images/medium/cb-2014-00567v_0005.gif'></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/cb500567v'>ACS Electronic Supporting Info</A></P>
